I tried to bend 3/8 steel fuel line once for this, and also found it to be difficult or impossible. People do it all the time, though. Is there an extra big tubing bender that is needed? Anyone care to post one they have used? The prices for pre-bent and braided don't look especially appealing to me. Don't know if the o.p. is on a budget or as cheap as I am, though. I'd get one from a junkyard before spending that kind of dough unless this is an extra nice machine.
